SPECIFICATION forming part of Letters Patent No. 376,722, dated-Tannery 17,1888.

Application filed October 20, 1887. Serial No. 252.896. (NoimodelJ 7 T0 all whom it may concern:

Be it known that I, EDGAR PEOKHAM, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in (Jar-Wheels, of which the following, taken in connection with the accompanying drawings, is a full, clear, and eX- act description.

This invention relates to the class of carwheels in which the body of the wheel is con-. strueted separately from the hub and the tire separately from the body.

My present invention consists in improved construction and combination of the constituent members of the wheel, possessing superior strength and stability, as hereinafter fully explained, and specifically set forth in the claims.

In the annexed drawings, Figurel is atrans- Verse section of a car -wheel, showing my improvements embodied in a wheel having a paper or other non-metallic core. Fig. 2 is a Fig. 3 is an enlarged detail view of the connection of the retaining-rings with the tire, and Fig. 4 is a sectional view of the tire-locking devices in connection with a metallic wheel-body.

Similar letters of referenceindicate corresponding parts.

H represents hub I form with a central circumferential'enlargement, H, upon which is seated the core B, of paper or other non-metallic material, said core being confined between the hub and outer ring, D, by the web-plates P P, secured to the ends of the hub enlargement H and sides of the ring D, as hereinafter described.

In order to enlarge the bearings of the core "B and to relieve the web-plates from thestrain due to the pressure of the flange of the tire against the side of therail, tending to crowd the tire off from the core B, I form the hub enlargement H with an outwardly-beveled peripheral face, h, and bevel the inner peripheral face of the ring D, preferably parallel with the bevel of the hub, and the core B, I provide witha central. eye, beveled to correspond to the bevel of the hub enlargement H, upon which it is seated, and the outer peripheral face of the core I bevel to correspond to the aforesaid beveled inner face of the ring D, as

. shown in Fig. 1 of the drawings;

the hub of the wheel. This undercut projection, e,

The plates P P are p the hub enlargement H by collars G O, mounted on the end portions of the hub and clamped against the sides of the aforesaid plates by bolts or rivets b, passing transversely through and hub enlargement. To properly cushion the wheel, I make the censaid collars, plates,

tral eyes, 6, of the plates P P of greater diameters than those of the end portions of the hub, and thus allow radial play of the plates and cause the non-metallic core B to carry theload which is thrown on the wheel. bolts or rivets b from shearing strain, I elongate the holes a a, through which they pass,

suitable non metallic material, between the ends of the hub enlargement H and adjacent portions of the plates P P the latter. are relieved from jars, which, tend to crystallize the metal. p

The plates R]? are secured to the outer ring, D, by the retaining-ring R, terior of one of said plates, ring R and locking-ring I, applied and the retainingto the ex secured to the ends of To relieve thev applied to the exf terior of the other plate and bolts or rivets d, passing transversely through said rings and plates. The inner circumferences of the rings R R, I make smaller than that of the ring D,

so as' to cause the rings R R to reach past the ring D toward the center of the wheel, audthus P P. T denotes the tire,

brace the plates which I secure to the body of the wheel by V formingthe tire with and forming the outer edge of the retaining-ring I spondingly-shaped outward projection, e,entering the undercut projection of the tire. Said retainingring It, being composed of wrought-iron or steel, affords a more secure an inward-proj ecting I R with a corre hold than the cast-iron ring D, which hitherto was formed with the interlocking projection e. Furthermore, in case of breakage theretaining-ring R is mucheasier renewed than the ring D and the body of thewheelis maintained' intact. At the opposite side .of the wheel I provide the inner peripheral face of the tire with a groove, 0, the inner side wall of which is undercut, an thereof is beveled, as shown at c. The retaining-ring Itv and looking-ring I, .I make of sufficiently greater circumference than the plate P d the outer side wall too 65 Q I and by inserting liningsl Z, of paper or other,

and ring D to project into the groove 0. The outer peripheral portion of the retaining-ring R, I form with an inward projection, f, entering the undercut side of the groove 0, and the outer edge of the locking-ring I, I bevel to correspond to the beveled side of the groove 0, into which it projects. In order to allow the rings R and I to be inserted into the groove 0, I divide each into sections, and first introduce the ring R, then insert the sections of the ring I, and in forcing the same into the beveled groove 0, I wedge the ring .R tightly in its seat in the groove, and thus securely lock the tire on the wheel. The bolts or rivets (Z (Z, passing through the sections of the rings R and I and through the plates P P and ring D, serve to firmly'unite all of said parts.

Having described myinvention,whatI claim as new, and desire to secure by Letters Patent, 1s-

1. The combination of the hub H, formed with the central enlargement, H, the webplates P P, embracing between them said enlargement of the hub and having their central eyes ofgreater diameters than the end portions of the hub, and provided with the elongated holes a a, the core B, seated upon the enlargement H of the hub, the collars O O, seated on the end portions of the hub, and bolts or rivets b b, passing through the holes a a and through the collars and fastening the latter on the web-plates, substantially as described and shown.

2. The combination of the hub H, formed with the central enlargement, H, and with a beveled peripheral face on said enlargement, the web-plates P P, embracing between them the enlargement of the hub, the core 13, provided with a correspondingly-beveled eye seated on the peripheral face of the hub, and the collars G G, seated on the end portion of the hub and secured to the sides of the webplate's, substantially as described and shown.

3. In combination with the outer ring, D, web-plates P P, and core B, the retaining-rings R R, having their inner circumference smaller than that of the ring D, substantially as described and shown, for the purpose specified.

4. The combination of the ring D, formed with a beveled inner peripheral face, and the core B, provided with a correspondingly-beveled outer peripheral face seated on the inner face of the ring, substantially as described and shown.

5. The combination of the hub provided ferential groove 0, formed with the beveled outer wall, 0, and the sectional locking-ring I, having its outer edge beveled correspondingly, substantially as described and shown.

7. In combination with the wheel-body, the tire formed at one side with the undercut inward projection, e, and provided at the opposite side with the groove 0, having an undercut inner wall and beveled outer wall, a, the retaining-rings R R, interlocking, respectively, with the undercut projection e and undercut wall of the groove 0, and the sectional locking-ring I, having its outer edge beveled and inserted into beveled portion of the groove 0, substantially as described and shown.

8. In combination with the wheel-body, the tire formed at one side of its inner peripheral face with the undercut inward projection, e, and the wrought-metal retaining-ring R, secured to the side of the body and formed with an outward-projecting flange, e, interlocking with the projection Z, substantially as described and shown.

9. In combination with the wheel-body, the tire formed at one side of its inner peripheral face with the undercut projection e and at the opposite side with the groove 0, the wroughtmetal retaining-ring R on one side of the body and formed with an outward-projecting flange, e, interlocking with the projection e, sectional retaining-rings on the opposite side of the wheel-body entering in the groove 0, and bolts or rivets securing said retainingrings to the body, substantially as described and shown.

In testimony whereof I have hereunto signed my name, in the presence of two witnesses, at Syracuse, in the county of Onondaga, in the State of New York.
